Exmark 109-7294 P21 Grass Bag 21 Commercial S Series

What It Is

The Exmark 109-7294 P21 Grass Bag is a 21-inch commercial-grade grass collection bag designed for Exmark Commercial S Series walk-behind mowers. It replaces worn or damaged OEM bags to maintain efficient grass clipping collection during heavy-duty mowing.

Fitment & Compatibility

• Deck size: Fits 21-inch cutting decks on Exmark Commercial S Series mowers (models like S21KS, S21KC, and similar S-series units).
• OEM vs aftermarket: This is a genuine Exmark OEM part (109-7294), not a third-party replacement. It matches original bag dimensions and attachment points.
• Measurement check: The bag is ~21 inches wide and ~12 inches deep; measure your existing bag’s mounting bracket spacing and hook placement to confirm fit.
• Model verification: Check your mower’s model number plate (under seat or on frame) and cross-reference with Exmark’s official compatibility list or your owner’s manual.

Key Things to Know

• Build quality: Heavy-duty polypropylene fabric resists tearing and UV damage, but it’s not indestructible—avoid overfilling or dragging across rough surfaces.
• Installation difficulty: Easy, tool-free swap—slides onto the existing bag bracket and secures with a latch. Takes under 5 minutes.
• Common gotcha: The bag’s rigid frame can warp if left in direct sun for long periods; store in a shaded, dry area.
• Performance: Holds about 2.5 bushels (roughly 20 lbs of clippings). The mesh panel allows airflow but may clog with wet grass—empty frequently in damp conditions.

Should You Buy It

Buy this if you own an Exmark Commercial S Series 21-inch mower and need a direct OEM replacement that matches original fit and durability. It’s ideal for pros or homeowners who want hassle-free compatibility and reliable grass collection without modifying brackets or adapters. Skip it if your mower isn’t an Exmark S Series (check model number first).
